摘　　要：分析了熔融沉积(FDM)快速成形工艺的扫描方式,建立了分区域穿梭扫描算法。基于已划分的实体填充路径和支撑填充路径区域,对其填充顺序提出了相对距离优化算法,并利用Microsoft Visual C++8.0作为开发平台,对优化后的综合填充效果进行了动态仿真。工艺实验证明:该扫描填充方式减小了样件翘曲变形的可能,大幅度减少了空行程,提高了FDM生产效率。Scan methods of Fused Deposition Modeling （FDM） were analyzed and arithmetic of zoning was put for ward. Based upon accomplished area of entity filling path and support filling path, arithmetic of relative-distance optimization was carried out. Dynamic simulation was done with the help of VC＋ ＋ 8.0. Technologic experiment shows that the scan method can reduce deformation of parts, decrease empty journey, and then improve efficiency of FDM.
